Heart rate variability (HRV) decreased soon after coronary artery bypass grafting and returned to the preoperative level within 2 months; however, HRV did not exceed the preoperative level, even 6 months after coronary artery bypass grafting. Although myocardial ischemia can be improved by coronary artery bypass grafting, HRV did not benefit from coronary artery bypass grafting within 6 months.
冠状动脉搭桥术后心率变异性（HRV）很快降低，并在2个月内恢复到术前水平；然而，即使在冠状动脉搭桥术后6个月，HRV仍未超过术前水平。尽管冠状动脉搭桥术可改善心肌缺血，但在6个月内HRV并未从冠状动脉搭桥术中获益。
